138 with length len. That code is converted to an index by dropping drop
139 bits off of the bottom. For codes where len is less than drop + curr,
140 those top drop + curr - len bits are incremented through all values to
146 new sub-table should be started. drop is zero when the root table is
147 being filled, and drop is root when sub-tables are being filled.
